Produced electrolytically via the Downs process, t
Produced electrolytically via the Downs process, this substance is used in a qualitative "fusion test" for nitrogen, sulfur, and halogens. This element's atomic spectrum features two lines at 589.0 and 589.5 nanometers, called the D-lines, which give it a bright yellow flame test. Often stored under oil because it oxidizes quickly in air, this element is a soft, silvery metal. Its bicarbonate is known as baking soda, its hydroxide is a strong base known as lye, and its chloride is called table salt. For 10 points, name this alkali metal with symbol Na.
